• the PICC supports ISO/IEC 14443-4 chaining to allow larger command or response

frames than the supported buffer size for variants of the following commands:

– Native commands wrapped into ISO/IEC 7816-4 APDU: ReadData, WriteData,

ReadRecords, WriteRecord, and UpdateRecord, see Section 11.

– Standard ISO/IEC 7816-4 commands: ISOReadBinary, ISOUpdateBinary

i.e. every command where larger frame size can occur.

• the PICC will automatically split a response in several frames to fit with the FSD frame

size supported by the PCD and communicated in the RATS.

When a PCD applies ISO/IEC 14443-4 chaining, see [3], it needs to assure the

reassembled INF field containing the command header (i.e. ISO/IEC 7816-4 header

bytes and/or (Cmd || CmdHeader)) fits within the PICC’s buffer (FSC) communicated in

the ATS. If not, the PICC may respond with LENGTH_ERROR.

The ISO/IEC 14443-4 chaining does not influence the secure messaging. This means

that the secure messaging mechanisms are applied as if the command or response

would have been sent in a single large frame. With regards to command execution,

commands are handled as if they were received in one large frame, except for write

commands where the total frame size can be larger than the supported FSC (WriteData,

WriteRecord, UpdateRecord and ISOUpdateBinary). In this case, command execution is

started before the complete command is received.

Note that this is important for StandardData files, where the file may end up in an

undefined state if the command is not completed successfully, see Section 8.6.
